2.6 Programmable Digital Input Functions
(Control terminal block inputs 1 through 5)
The function of the digital inputs 1 through 5 are programmed via the corresponding
parameters: C01 [
DIGITAL INPUT 1] through C05 [ DIGITAL INPUT 5]. The following
programming guidelines must be followed:
• No two inputs can be programmed for the same function.
• The PTC input (setting 19) is only programmable on input terminal 5.
The digital inputs can be programmed to respond to NO (Active High) or NC (Active
Open) inputs via parameters C11 [
DIGITAL INPUT 1 LOGIC ] through C15 [ DIGITAL INPUT 5
LOGIC ].
Table 2.5 describes the programmable digital input functions.
!
ATTENTION: All digital inputs respond to level sensitive commands.
Inputs do not require a voltage transition (cycle) after a fault condition is
cleared, after input power cycling, or after programming the logic of the
digital input.
All digital inputs can be programmed as NO or NC. However, the start
command should be set as NO (active high) and the stop command
should be set as NC (active open). If set opposite of this, an inadvertent
start or failure to stop could occur should a discrete connection be lost
or control wire come loose. If the user chooses to disregard this safety
practice - the risk assumed by the user can be reduced by assuring that
other safeguards are used to insure proper start and stop operation.
Depending on the application: This may include appropriate emergency
stops, redundant wiring, electronic guards and/or mechanical guards.
Failure to observe this precaution could result in severe bodily injury or
loss of life.
